Recipe: Crush 30g zinc chloride and 30g copper nitrate together with pestle and mortar with one or two drops of water to make a paste. Brush on to copper object and let sit for 3 hours. Rinse the object gently in cold water and leave in the daylight. The colors are very pale at first but darken over time. This one turned out like a tiny cosmos. Lovely.
Copper plate just after rinsing.
Plate after being left out for a few days.
